Eva Longoria opens up on her 'über private' boyfriend Jose Antonio Baston

Super stylish Eva Longoria has got some competition — from her boyfriend Jose Antonio Baston.

"He's a good dresser," the actress said of her man during an appearance on the Ellen DeGeneres Show this week. "I always have to step it up. It's exhausting."

Eva, 39, wasn't giving much away about her blossoming romance with 45-year-old Jose, president of Televisa, Latin America's largest media company. "He's über private," she said, before telling her host she is "very happy".

Last month, the Desperate Housewives star told Parade magazine about the qualities she looks for in a partner.

"You know, in general I'm attracted to humour and intellect in a man," she said. When asked whether her Mexico-based boyfriend had both of those things, she replied with a laugh, "Sure. Let me tell you, I'm very lucky in my life."

Eva and Jose have been dating since late last year. They made their first red carpet appearance in November when Jose escorted Eva to the Museo Jumex Opening dinner at Case De La Bola in Mexico City.

"He's been sweeping her off her feet and courting her like a proper gentleman," a source said.

Prior to her romance with Jose, Eva dated Ernesto Arguello — their relationship came to an end in August after four months of dating.

She split from Eduardo Cruz, Penelope Cruz's younger brother, in March 2013.
